Class of Equipment
Fluorinated Greenhouse Gases
Compliant with REGULATION (EU) No 517/2014 OF THE EUROPEAN PARLIAMENT AND OF THE
COUNCIL on fluorinated greenhouse gases.
This product contains fluorinated greenhouse gases in a hermetically sealed system. This product contains foam
blown with fluorinated greenhouse gas, R-245fa. If a leak in the sealed system is detected, the operator shall repair
without undue delay.
For ULT models rated 230V/50Hz, intended for import into the EU, the following sizes are designed for use
with the following amounts of fluorinated greenhouse gases:
1 Installation category (overvoltage category) defines the level of transient overvoltage which the instrument is designed to withstand safely. It
depends on the nature of the electricity supply and its overvoltage protection means. For example, in CAT II which is the category used for
instruments in installations supplied from a supply comparable to public mains such as hospital and research laboratories and most industrial
laboratories, the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V supply.
2 Pollution degree describes the amount of conductive pollution present in the operating environment. Pollution degree 2 assumes that
normally only non-conductive pollution such as dust occurs with the exception of occasional conductivity caused by condensation.
